(iii) The compressibility ratio factor "s" used in

computing the volume of Gas delivered through a

turbine meter or a positive displacement meter

shall be determined by the equation s = (Fpv)2 in

which "Fpv" is the supercompressibility factor

determined as described in Section 7.4(d).

 

(e) In determining the flowing temperature factor,

supercompressibility factor, and compressibility ratio

factor "s" for use in computing the volume of Gas

delivered through a meter, the flowing gas temperature

for only the period(s) of time that Gas was flowing

through the meter shall be used.

 

7.5 All flow, measuring, testing and related equipment shall be

of standard manufacture and type approved by Midwest.

Midwest or Shipper shall have the right to be present at

the time of the installing, reading, cleaning, changing,

repairing, inspecting, testing, calibrating or adjusting

done by the operator of the measuring equipment. The

records from such measuring equipment shall remain the

property of the operator, but upon request, the other party

may request records, including charts, if any, together

with calculations therefrom for inspection, subject to

return within thirty (30) Days after receipt thereof.

Reasonable care shall be exercised in the installation,

maintenance and operation of the measuring equipment so as

to avoid any inaccuracy in the determination of the volume

of Gas received and delivered.

 

If, upon any test, any measuring equipment is found to be

in error, such errors shall be taken into account in a

practical manner in computing the deliveries. If the

resultant aggregate error in the computed receipts or

deliveries is not more than 0.5% for chromatograph or

calorimeter and two percent (2%) for other measuring

equipment, then previous receipts or deliveries shall be

considered accurate. All equipment shall, in any case, be

adjusted at the time of test to record correctly. If,

however, the resultant aggregate error in computing

receipts or deliveries exceeds 0.5% for chromatograph or

calorimeter and two percent (2%) for other measuring

equipment, at a recording corresponding to the average

hourly rate, of Gas flow rate for the period since the last
